I thought about this as I wrote my reply, and concluded that yes it's important, but that too is usually a rounding error. I'm all for feeling good about what you've done in the world, but for most of us whose names aren't going to be repeated for centuries it's a drop in the ocean and only becomes less relevant over time. Even something like parenting, which I don't think any of us will argue is not important. Each generation that goes by, your relative contribution is halved. I'll bet most of us can't tell very many stories about great-grandparents, for example. And we have twice as many great-great-grandparents, etc., which even fewer of us will be able to keep track of. So even as a father, while I try to do the best job I can, I have to admit that's going to happen to me too, and any impact I can have through parenting is going to be blended with an exponentially growing set of people. That's not bad, that's just how it works. I'm not saying you shouldn't enjoy life or be ambitious or do a good job in the things that you do, or that helping people and doing big things is not worth it, but at some point we'll all likely have to humbly admit it: we aren't as important on the individual scale as some would like or expect. |
I prefer a different way of measuring contribution: suppose that (for simplicity) the checkpoints on the progress of humanity are fixed and the only difference you can make is to delay or accelerate reaching the next checkpoint. Your contribution is how much time you've won or lost for humanity. Then contribution stops being relative – if you've made future happen five years earlier, this is permanent, period. Your children and grand-children will arrive into their respective futures five years earlier, too, because of you.
> that too is usually a rounding error.
There are no rounding errors! Why do you think that just because you can see how much you've influenced one person thru parenting, but can't see how you influenced the entire world thru your actions, the first influence is somehow “bigger”? Yes, it's epsilon, but it's epsilon × world. And the world is big.
(By the by, the same logic applies to voting – yes, your contribution to the final decision is small, but since the decision itself is so important, in the end your contribution doesn't turn out to be less than contributions from your other decisions.)
